Printing apparatus

A recording device includes a sandwiching member coming into contact with a first guide shaft at a guide shaft-side contact surface and disposed between a carriage and the first guide shaft in a second direction and a cam member coming into contact with a first curved surface of the sandwiching member and configured to rotate about a first direction as a rotation axis relative to the carriage in a state of being engaged with the carriage. The cam member presses the first curved surface with the second curved surface slidably fitted to the first curved surface in the second direction and changes a position of the carriage relative to the sandwiching member in the second direction as a distance in the second direction of a position at which the second curved surface presses the first curved surface relative to the rotation axis changes along with rotation of the cam member.

Recording device

A recording device is a recording device receiving liquid supplied from a liquid accommodation unit, and includes a recording unit configured to eject the liquid onto a transported medium, a support unit configured to support the medium at a position facing the recording unit, a first side frame and a second side frame that are configured to support one end side and the other end side of the support unit, a coupling frame configured to couple the first side frame and the second side frame, and a holding unit configured to hold the liquid accommodation unit. The coupling frame is located below the support unit, and the holding unit is located between the support unit and the coupling frame and between the first side frame and the second side frame.

Provided is a printing apparatus including: a holder unit provided with a holding member, a contact portion, and a shaft member, and an apparatus body provided with a support portion, and a fixing portion, wherein the shaft member is configured to be detachably attached to the support portion, the holder unit is configured to be rotatable between a first position and a second position with reference to the shaft member in a state where the shaft member is supported on the support portion, the first position is a position where the shaft member is attached to the support portion, and the second position is a position where the apparatus body fixes the holder unit by the fixing portion, the second position being a position where the contact portion is separated from the installation surface.

A printing apparatus according to the present disclosure includes a biasing member that applies a force in a &#x2212;Y direction, a motor supporting member including a reference surface and an inclined surface inclined so that a distance between the reference surface and the inclined surface gradually decreases in the &#x2212;Y direction, and a motor including an abutting member configured to abut on the reference surface and the inclined surface. By applying the force in the &#x2212;Y direction from the biasing member to the motor, the abutting member abuts on the reference surface and the inclined surface.

Printing apparatus and motor

A printing apparatus includes a transport unit configured to transport a printing medium, a platen that includes a first support surface supporting the printing medium, a light-emitting unit configured to emit detection light toward a transport path of the printing medium, and a light-receiving unit provided adjacently to the light-emitting unit and configured to detect reflected light of the detection light, wherein a recessed portion is provided in the platen, the recessed portion including a primary reflection surface receiving the detection light and a secondary reflection surface receiving the detection light reflected by the primary reflection surface, and the first support surface and the secondary reflection surface overlap in an optical axis direction of the detection light.

A printing apparatus includes a printing unit configured to perform printing onto a printing medium, a driving roller configured to provide a transporting force to the printing medium, a plurality of driven rollers configured to press the printing medium, which is transported by the driving roller, and configured to rotate in conjunction with a movement of the printing medium, a plurality of support members each being configured to support a roller shaft serving as a rotation axis about which each of the plurality of driven rollers rotates, a base body to which the plurality of support members are attached, and an attachment/removal mechanism configured to cause the plurality of support members to be removably attachable individually to the base body.

A recording device includes a medium support portion, a recording head configured to eject a liquid toward a medium supported by the medium support portion, a gantry that includes the recording head and is configured to move relative to the medium support portion in a Y-axis direction, a first linear scale attached to a first attachment member, a first encoder configured to read markings of the first linear scale while moving, together with the gantry, relative to the medium support portion in the Y-axis direction to detect a displacement of the gantry, and a length adjustment unit configured to adjust a length of the first linear scale attached to the first attachment member, by adjusting a tension in the Y-axis direction applied to the first linear scale.

A motor unit includes a motor including a motor side output shaft extending in a Z direction, and a reduction drive, wherein the reduction drive includes a housing, a reduction drive side output shaft extending in the Z direction, a toothed gear group configured to transmit rotation of the motor side output shaft to the reduction drive side output shaft with the rotation being decelerated, and a deformation sensor configured to detect deformation occurring due to vibration of the motor.

Motor unit and printing apparatus

A filter unit is a filter unit disposed in a printer including a control unit, and includes a filter configured to trap a foreign material, a frame configured to hold the filter, and a storage element provided on the frame and capable of transmitting/receiving information about the filter to and from the control unit.

Filter unit, light source unit, printer

A printer includes a platen including a loading surface on which a target printing medium is loaded and in which through holes are formed, a printing unit performing printing on the target printing medium, a platen stand on which the platen is loaded, the platen stand including air chambers communicating with the through holes, communication tubes that individually communicate with the air chambers, an air blower configured to suck and exhaust air in the air chambers, and suction opening/closing valves individually provided in the communication tubes, the suction opening/closing valves configured to open and close communication between the air blower and the plurality of air chambers.
